UPDATE: Finally (on 10th Dec.) we might get those results from Juno's Earth flyby http://phys.org/wire-news/147545245/agu-fall-meeting-press-conference-schedule-briefings-streamed-on.html
There is an unique opportunity for ToEbi coming on October 9! The spacecraft of Juno mission makes Earth flyby at that date. One thing that is closely looked at is the so called flyby anomaly. Contemporary physics can't explain the phenomenon but ToEbi can! I'm going to give an exact prediction on how big the acceleration change for the spacecraft will be. Of course, I don't know all the mission details so I have a three scenarios.
Quote from SPACEFLIGHT101:
During its mission, Juno spins at different rates depending on mission maneuvers. During Cruise, Juno makes one rotation per minute, during science operations, the spin rate is 2rpm and for Main Engine Burns, the spin rate is increased to 5rpm.
Ok, what will be the spin frequency during the flyby? Probably that 2 rpm. After all, they are going to do some science operations near Earth, right? And why would they use the Main engine (even though it would give the biggest boost )? Anyway, here are the predictions for all those three different spin frequencies (Disclaimer: The spin plane of Juno must point towards Earth's core during the closest part of the flyby). Based on previous flybys, my prediction is at perigee. Anomalous speed increase is in case of
- 1 rpm: 0.278 mm/s
- 2 rpm: 1.111 mm/s
- 5 prm: 6.944 mm/s
Calculations are based purely on spin frequency of the spacecraft. Newton's gravitational equation rules Juno's behaviour during the closest part of flyby
but based on ToEbi it should be
in other words
Gravitational slingshot is a perfect elastic collision so the difference between expected zero (actually it might be mm/s) and measured speed increase must depend on spin frequencies of the spacecraft and Earth (which are not considered as relevant variables in case of elastic collisions), there is no other variables explaining the phenomenon so well. In normal conditions during a flyby, spacecrafts using reaction wheel mechanism (no spinning used) won't gain any anomalous speed increase (except that possible mm/s).
Update: Measurements considering flyby anomaly start seven days earlier and end seven days after the flyby. Therefore we are going to get the results not earlier than Oct. 17.
Update: Interesting to see how the triggered safe mode effected the flyby anomaly. If I understood correctly Juno's attitude changed towards Sun due to safe mode. That kind of maneuver breaks the symmetry of flyby, especially during the closest part of flyby. However, the first half of the flyby went normally.
Update: Total anomalous speed increase would be something like 2.2 mm/s if 2 rpm spin frequency was kept during the whole flyby. However, Juno went into safe mode after 10 minutes from the closest approach. During safe mode, Juno takes an attitude towards Sun. Was spin frequency changed to 1 rpm? What was the new spin plane angle towards Earth? I can't give decent prediction for the total anomalous speed increase due to lack of information.
